Nothing of that sort is claimed; just because you do not have a fool proof method doesn't mean you take limited steps to stop it. The least you can do is put hygiene checks. Most reputed conferences wouldn't even do that. Also, how and why is this a feel-good policy? The program committee of the conference is reputed enough to check for fraud/discrepancies. After all, the Stapel fraud (like many others) was detected by his peers. FYI - this is not a journal either.
